- Ancient Dragon, Tyrannolegend could only be used in a full Ancient Dragon sub-clan deck because Tyrannolegend can only retire Ancient Dragon units for it's limit break as well as for its especial counterblast with Ancient Dragons.
- You can use Ancient Dragon, Babyrex and Ancient Dragon, Iguanogorg to be retired by Tyrannolegend's limit break and activate their skills being retired to superior call new units for another attack.
- This card can reach full potential by break ride on top of Ancient Dragon, Spinodriver and perform especial counterblast of Tyrannolegend twice and reaching power of 41k with 3 crits without being boosted and can reach up to at least 52k with a boost from Savage Warrior .
- You can use both of this card's skills at once, as they have different costs.
